Specification of "Letters Patent.

ilntented June 30, 19M.

Application filed .Tune 12, 1909. Serial No. 501,733.

l 0 au w/wmy er may concern Be it known that I, RonERT L. Cooney', a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Pneumatic @leaning-Tools, of which the 4following is i. specification, reference being had lto the accompanying drawing, forming e part thereoff This invention .relates more particularly to handles for tools of this class, its main ohjects being to facilita-te the; passage and movement of the tools between, around and uiiderneath obstructions such as the legs oi tixtures or furniture, and to render their operation more eii'eetive.

It consists in the construction, arrangeL 'ment and combination of parts as .hereinat'ter particularly described and pointed out in the claims. l n

in the accompanying drawinghlxe char acters designate the same parts in both fig ures. V

ligurel is a perspective view, and Fig; 2 is at pien view of e tool embodying the invention illustrating the manner of using the tool for sweeping underneath a, row of school desks, and Figs. 3 and 4 are enlarged detail sectional views of the swivel joint connections at the ends of the tubular operating arm and exhaust conduit.

' For the 'purpose of illustration and explanation, the invention is shown in connection ,with a floor sweeper, although the tubular operating erm and its connections constituting; the essential features of the invention, may be used with cleaning heads or nozzles of various forms designed for various kinds of Work.

iteferrine to the drawing, a desi mites the head or body of the sweeper provi ed with u tubular shankb, which is hinged or pivoted to the back transversely to the axis of the shank. It is also roviiied in the present ease at the ends witg] brushes or iiexible extensions c for working close to ,the legs or bases of fixtures, furniture or other objects Without marring the same.

d is a tubular operating arm and exhaust conduit havin at one end a swivel joint conneetion e Witi the tool heed or shank, and adjacent to the same end a double reverse bend or offset f. At the opposite end it has a swivel joint minneetion f7 with a coupling piece /1 for the attachment oi' hose '11, by which the tool is connected with a. pump or other air exhausting means. These swivel joint connections may he inode as shown in Figs. il Vand l, and each consists of a severed spring ring l which fitted to turn and `coupling piece It is )reterebly and usually provided withn han le j, toaid in the rnenipulation of the tool. The erin` l isnt@ vided preferably adjacent to", the'- con )ling piece l/L and handle, with a' hund grip for turning it into different positions,

ln theopcration of it totulol "t'liieilrind in 'sweeping under a row of school desks as illustrated in the drawing, the bend or odset oi' the arm 22 is turned out as indicated by dotted lines in Fig. 2, to facilitate inserting the head or body a of the tool between the legs oi: udjncent desks at one end thereof. With an arm of sulicient length the floor underneath a number of desks may be thoroughly end quickly 'swept without removing and renteringl the tool foiyevery desk or at short intervals, as would be re quired if o short, straight handle or urin wes used.

As the tool is moved back: and forth underneath the tutti ot desirs it may lie carried or shifted from one side to'-the other so as to work close to either row of legs by turning the arm zZ in its swivel joint connections with the head a and coupling piece ft so as to reverse the bend or oii'sct f. 'The bend or offset f in the erm (l permitsthe tooll to pass between obstructions and to 4vvorlt in luces where it could not'otherwise be need, esides greatly facilitating its operation around obstructions and within restrieted spaces.

The pivot or hinge connection of the tubular shank b with the tool head or body a, and the bend or offset f of the erin ai in connection with the swivpl nime a+. the ends l lign! thereof` admit of the use of the tool u'nderi neath furniture, tixiures or other objects where the vertical as well as the horizontalspace is so limited that it could not be otherwise employed. The bend or offset and the swivel joints at the ends of the tubular arm 'thus coperate .ith the hinge or pivot between the shank b and the tool head a in atording adjustments whereby the tool may he etl'cctively used iii-limited spaces where it could not otherwise be successfully operated.

lclaizn:

l. A pneumatic cleaningtool provided with a tubular operating arm having a swivel connection with the tool head, and having a double reverse bend adjacent to said connection, whereby the tool may be shifted to oneside or the other relative -to said arm, by turning the latter around its axis without materially changing the angoi-V materially changing the angular relation ot the tool to a straight line passing throug the ends of said arm.

2?. In a pneumatic cleaning tool the com?,

bination Jwitha tool head and a hose/cow.`

pling` o f a tubular arm having swivel joint" connections with said head and couplingf', and having a double reverse bend adgacent to the tool head, the axes of rotation of said connections being approximately parallel.

-,i. In a pneumatic cleaning tool the com-v bination with the tool head'liaving a tubular shank pivoted thereto transversely to the axis ot' the shank and a hose coupling, of a tubular operating arm havingswivel joint connections at the ends with said shank and coupling and having a double. reverse 4bend adjacent to said shank.

In a pneumatic cleaning tool the combination with the tool head having a tubularshank pivoted thereto tran verseiy to the axis ot the shank, of a tubulin operating arm having a swivel joint connection with said shank and having a double reverse bend adjacent-to said shank.

In witness whereof I hereto affix my signature in presence of two witnesses.
